Have you tried picking Mallika when the color STARTS to break towards yellow? If I pick when the shoulder has some yellow and give them a week to 10 days they are great. If they are more than 25% yellow when picked they can sometimes have some carrot overtones. One year I picked some later that were over 75% yellow. After a couple days on table they actually tasted like orange creamsicles. Only in that one instance have I ever tasted citrus/vanilla flavor from that variety.
If you pick them near fully colored they are 50-50 might taste fine or may have the mango death funky flavor.
